I have a bunch of nozzles for my hypertherm 45m torch.Trying to cut 1/4 inch material foes not penatrate at book specs.I haven't seen any different part number to order other than what I have.TrI'd slowing down and different voltages.hmm.

The operators manual lists all of the available parts for the Powermax45. There are no Finecut parts for this system. Finecuts are designed for thin gauge with a maximum thickness of 10 gauge (1/8")....so they would not help on 1/4" anyway. Here are the available mechanized consumables. Be sure the part numbers you have match up with these. The Powermax45 will have no trouble piercing and cutting up through 1/2" steel. If you cannot penetrate 1/4" then you may have the wrong consumables, you may have a bad work cable (check connections for continuity), or you could have a missing or damaged torch oring or low inlet air pressure.

follow up on this topic.I have learned a lot.first good clean air. no moisture. adequate air also.also had to learn the software to control plunge while piercing.Haven't tried any consumables accept hyperthermthings getting better as I learn to fine tune

Finecut's might not be rated for 6mm but they don't half cut it well! a nice slow speed at 1200mm/min cuts those intricate bits A1.They really are a godsend.The new duramax torch a very worthwhile upgrade for the 45 machine, far more consistent cuts using the 45a parts as well.
